Substances X, Y and Z can all act as oxidizing agents. In Colution X is Violet Y is Yello and Z is green. In the reactions they undergo thay are reduced to X- Y- and Z-, all of which are colorless. When a solution of Y is mixed with one containg X- ions the color changes from yellow to violet. Required:
a. What Species Is oxidized? (X-)
b. Which Species is reduced(Y).
c. When a soulton of Y is mixed with one containing Z- ions, the solution remains yellow.
d. Is Y a better oxidizing agent than Z?
e. Is Y a better oxidizing agent than X?

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
